Clonazepam Level (Blood)

Does this test have other names?

Klonopin level

What is this test?

This test measures the amount of clonazepam in your blood.

Clonazepam is a drug used to treat seizures. It's often prescribed to adults and children who suffer from partial seizures and spasms. It may also be used to treat panic attacks.

Why do I need this test?

You may have this test if it's possible you have taken an overdose of clonazepam. The test can also be used to monitor the level of clonazepam in your system throughout treatment.

You may also have this test if you are having side effects from clonazepam, such as drooling, sleepiness, lack of muscle coordination, difficulty breathing, suicidal thoughts, and drowsiness.

What other tests might I have along with this test?

Your doctor may also order other tests, including:

  • Complete blood count, or CBC

  • Liver function tests

What do my test results mean?

Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider.

Results are given in micrograms per milliliter (mcg/mL). Therapeutic drug levels can range from 0.02 to 0.08 mcg/mL. Any level over 0.08 mcg/mL is considered toxic.

How is this test done?

The test requires a blood sample, which is drawn through a needle from a vein in your arm.

Does this test pose any risks?

Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore.

What might affect my test results?

Taking valproate and phenytoin may affect your results.

How do I get ready for this test?

You don't need to prepare for this test. But be sure your doctor knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illicit drugs you may use.
